Abstract:

As with any state highway agency (SHA), the construction needs exceed the budget limitations, which mandates that SCDOT prioritizes transportation project needs based on benefit/cost considerations. It is important to use every penny as wisely as possible. In such context, an early-stage cost estimate is imperative for evaluating the feasibility of large construction projects. There are currently no standard procedures implemented for developing planning-phase cost estimates across SCDOT offices. This research study developed a preliminary cost estimating tool (PCET) based on bid data gathered for over 325 past or ongoing transportation projects in South Carolina. The PCET tool enables planning personnel to rapidly develop both deterministic and probabilistic cost estimates. Three project categories were prioritized in this study, namely, widening, bridge replacement, and intersection improvement projects. Various project characteristics that transportation agencies would have data for in the planning phase are used as inputs to the PCET tool. The Microsoft Excel-based PCET tool is developed based on a combination of linear regression and machine learning algorithms. The PCET tool also includes an option to produce an early design stage cost estimate for the same three types of projects identified previously.
